Can nucleolus be found in prokaryotes
WebIn eukaryotes, ribosomes form in the nucleolus, a structure inside the cell’s nucleus. As ribosomal proteins enter the nucleus, they join with four rRNA strands to create a complete ribosome. The subunits exit the nucleus through pores and begin protein synthesis in the cytoplasm of the cell. In prokaryotes, proteins combine with three rRNA ... WebApr 28, 2024 · Nucleoid Definition. The nucleoid is the space within a prokaryotic cell where the genetic information, called the genophore, is found. Prokaryotes are divided into bacteria and archaea, which are both unicellular organisms that contain no membrane-bound organelles. The nucleoid, then, also has no membrane around it.
